Encryption is a method of coding information or sensitive data or asset, to prevent unauthorized users from accessing it. Currently, it is essential to secure data that is at rest in our computer or is transmitted via web against attacks. Several of cryptographic techniques are being used to preserve security and could be classified as: symmetric and asymmetric. A symmetric algorithm named as Advance Encryption Standard (AES) is selected for enhancement due to its applicability and widely used algorithm. In AES, among the four stages that are used for encryption and decryption, Sub Bytes and Mix Column produce more delay. From the two, mix column accounts 60% of the whole delay. To overcome these challenges, in the designed symmetrical cryptography algorithm mix column stage is replaced by bitwise reverse transposition technique. This helps to improve the speed efficiency of the existing Advance Encryption Standard (AES) and Modified Advance Encryption Standard (MAES) algorithm. The simulation result of our Bitwise Reverse Transposition technique resulted in better encryption speed and decryption speed time when compared with original Advance Encryption Standard (AES) and Modified Advance Encryption Standard (MAES): 128.953% and 115.4% encryption and decryption speed performance. This is because of bitwise reverse transposition. Taking average of ten trials; 140.8% increased the throughput because of bitwise reverse transposition. Hence, our proposed Enhanced-Efficiency Advanced Encryption Standard (EE-AES) has better encryption and decryption speed performance and throughput when compared to original Advance Encryption Standard (AES) and Modified Advanced Encryption Standard (MAES).
